both freetds and unixODBC try to find a DSN
in these files, in this order:
 $ODBCINI
 $HOME/.odbc.ini
 /etc/odbc.ini

freetds will, however, expect to find the DSN
in the first file it can open. If the file exists,
but does not contain the requested DSN section, it
fails.

unixODBC behaves correctly, if it does not find a
DSN within a file, it continues to search the next
file.

This realy hurts when you have a system DSN in /etc/odbc.ini,
and no $HOME/.odbc.ini. If that is the case, unixODBC will
create an empty $HOME/.odbc.ini. freetds will then open that
file and not find the DSN in it.
